Choosing between lab balances scales often comes down to a simple question: do you need to weigh today, or can you take on a repair project? The first option is a working analytical balance. The second is a high-capacity precision balance sold for parts or not working. Both are aimed at biological lab work, but they lead to very different buying decisions.
Quick verdict
If you need a functioning balance with analytical-level resolution and don't want to troubleshoot, the Citizen CX 220 is the one to buy. If you can repair a non-functional instrument and want a larger weighing range, the METTLER TOLEDO MS4002TS/00 is worth considering as a project. The comparison table below gives the concrete specs; the details below explain why the condition difference matters.
At a glance
| Product | Price | Balance Type | Capacity | Condition |
|---|---|---|---|---|
| Citizen CX 220 | $699.99 | Analytical Balance | 220 g | Used, tested and working |
| METTLER TOLEDO MS4002TS/00 | $199.95 | Precision Balance | 4,200 g | For parts or not working |
Where each product wins
The Citizen CX 220 wins on readiness and resolution. It powers on, zeros correctly, and responds to weight. With 0.1 mg readability and a glass draft shield, it suits fine weighing tasks that need tight resolution. The power adapter is included.
The METTLER TOLEDO MS4002TS/00 wins on capacity and entry price. Its maximum weight is much larger than the Citizen's, and its price sits roughly $500 below. That tradeoff makes sense only if you can repair it: the unit powers on but does not load its application.
Product notes
Citizen CX 220 Analytical Balance 220g x 0.1mg Precision Laboratory Scale
At $699.99, the Citizen CX 220 is the option that gets you back to weighing immediately. The unit powers on, zeros to 0.0000 g, and responds to weight. The 220 g capacity with 0.1 mg readability is well matched to fine analytical work, and the glass draft enclosure helps reduce the effect of air currents while weighing. The display, controls, weighing pan, and power adapter are all present. That said, it is a used instrument with normal cosmetic wear, and the capacity is limited to 220 g, so it will not suit heavier samples. It also carries the higher price, which makes sense if you need a working balance now rather than a repair project.
METTLER TOLEDO MS4002TS/00 Precision Balance 4,200g | P&R
The METTLER TOLEDO MS4002TS/00 is sold for parts or not working at $199.95. It is a precision balance with a 4,200 g capacity. The unit powers on, but it does not load its application, and the load cell was not tested. Cosmetic condition is C2 used poor: the rear static footing tip is chipped, and the plastic ring around the weigh pan is cracked through on one corner. The display and ports are in good shape. If you have the ability to diagnose and repair lab balances, this could be a lower-cost starting point for a high-capacity unit. If you need accurate readings right away, the non-functional status is a hard stop. This is a repair purchase, not a plug-and-play balance.
Final choice by use case
Choose the Citizen CX 220 if you need a ready-to-use analytical balance and your samples fit within its capacity.
Choose the METTLER TOLEDO MS4002TS/00 if you need a larger weighing range and can repair or troubleshoot a non-functional unit, and if the price gap matters more than out-of-the-box readiness.
